Periodontitis, inflammation of the gums, you do not want to have these and you do not even have to. They can be prevented beforehand. Clean your interdental spaces at least once a day with a high-quality dental floss. But not by "sawing", but by gently placing them around each tooth and then gently moving them up and down. And not just after the steak you had for dinner but every evening. With the help of a dental floss,you remove deposits which you oftentimes oversee with the naked eye. But they can do a lot of harm, as they say.
